Hi,

I am getting the error shown below while using 'mapdl.aplot()' command to plot areas.

KeyError: '_canvas_manager'

During handling of the above exception, another exception occurred:

TraitError: The '_canvas_manager' trait of a ViewInteractiveWidget instance must be a _CanvasManager, but a value of class 'NoneType' (i.e. None) was specified.

Please let me know how to fix this.

Thanks in advance,
Balaji

It seems a pyvista issue.

Can you share a minimum working example?

Probably it is better if you create a new issue from this, filling all the issue fields.
